Abstract

The purpose of this study was to examine whether intermittent stretching accelerates amelioration on limitation of ankle joint mobility and disuse muscle atrophy in immobilized rat soleus muscle. Male Wistar rats (n=30) were divided randomly into control (C, n=5) and experimental (n=25) groups. In the experimental group, bilateral ankles of each rat were fixed in full plantar flexion with plaster casts for 4 weeks. The experimental group was divided into 3 subgroups: 1) immobilization alone (Ⅰ; n=5), 2) spontaneous recovery (no stretching exercise) for 1 (n=5) or 2 (n=5) weeks after cast removal (NS), and 3) stretching exercise for 30min/day (6 days/week, 1 cycle/4 s) for 1 (n=5) or 2 (n=5) weeks after cast removal (S). Range of motion on dorsiflexion was significantly higher in S than NS. Muscle fiber cross-sectional area of soleus muscle was significantly decreased in Ⅰ compared with C, and was significantly higher in S than NS. Numerous necrotic fibers were apparent in NS than S. These findings indicate that intermittent stretching accelerates amelioration on limitation of joint mobility and disuse muscle atrophy.
